The rapid ecological shifts that are occurring due to climate change present major challenges for managers and policymakers and, therefore, are one of the main concerns for environmental modelers and evolutionary biologists. Species distribution models (SDM) are appropriate tools for assessing the relationship between species distribution and environmental conditions, so being customarily used ...

Many excitable tissues are able to develop action potentials in the absence of any salt of univalent cation in the external medium. Osterhout and his associates' have shown that Nitella cells, which have been rendered inexcitable by prolonged immersion in distilled water, regain their excitability when calcium salts are added to the external medium. Fatt and Katz,2 Hagiwara, Chichibu, and Naka,...

The paper sets out to explore boundary conditions for process effects (that affected persons’ reactions towards authoritative decisions are affected by the way decisions are made). First, to find out whether decent authorities in search of acceptance for difficult decisions can gain from choosing the one or the other form of decision-making, we analyze the effects of different legitimate proced...

A series of ferrocenyl surfactants was tested as model compounds to study electron transfer reactions involving structural Fe(III) in clay minerals. The surfactants contain trimethylammonium headgroups, ferrocene tail groups, and intervening hydrocarbon chain lengths of one, six, or 11 carbons. Two factors considered to be decisive for electron transfer were addressed: (1) physical access of th...

in this study, the reliability of the primary gold mineralization exploration using multispectral etm+ imagery was investigated in lahroud region, northwest iran, which was conducted by integration of alteration and structural indicators. co-occurrence of the clay minerals and iron oxides is an important criterion in gold deposit exploration; therefore, their alteration zones were mapped using ...

this paper will examine how muslim intellectuals, as a result of their attachment to the doctrine of divine unity (taw¤hīd), the quran, sunnah of the prophet muhammad, and the doctrines and methods of sufism, were largely responsible for the restating of the perennial philosophy in the west in the twentieth century. the article consists of four sections: an introduction to the term 'philos...

The interaction of Fe2+ ion with Pyrazole was theoretically studied by Gussian 03, software at HF/(LanL2DZ+6-31G) and HF/ (LanL2DZ+6-31G (d)) levels in gas phase and solution. In this study acompartion between optimized structures of Pyrazole molecule in aspect of thermodynamicparameters such as enthalpy (H°), Gibbs free energy (G°) and entropy (S°) in presence of metallic ion(Fe2+), was perfor...

leaving one’s parental home disrupts place attachment, described as the affective bond or link between one individual and a specific place and/or the people living in that place. in other words, because students move away from their parents, their friend and their hometown, their bonds with these people and their hometown are disrupted. although moving disrupts place attachment to their hometow...

After more than a century since its birth, Quantum Theory still eludes our under1 standing. If asked to describe it, we have to resort to abstract and ad hoc principles about 2 complex Hilbert spaces. How is it possible that a fundamental physical theory cannot be de3 scribed using the ordinary language of Physics? Here we offer a contribution to the problem, 4 providing a short non-technical p...
